Trichoderma harzianum and Fe Spray Improve Growth Properties of Spathiphyllum sp.

Effects of fe and trichoderma harzianum bi strain on plant growthand development of spathiphyllum were investigated. experiments werecarried out in an glasshouse and in pots filled with soil, perlite and coco peat(1:1:1) were used as the growing medium. plant roots (seedlings with threeleaves) were inoculated with trichoderma (0 and 8% w/w) as media mixture.fe spray (0, 0.75, 1.5, 3 g/l), was applied 3 times on a month interval aftertrichoderma inoculation. factorial experiment was conducted in a completelyrandomized design with 3 replications. after six months, the plants weresampled for growth comparisons. based on results trichoderma improvedmorphological characteristics (p?0.01). there were differences between theuntreated control and the treatments for all of the growth parameters with theexception of spathe area and number of flowers. fe spray and intractionbetween trichoderma and fe significantly increased all morphological growthparameters with the exception of spathe area, leaf area and number of flowers.by applying terichoderma sucker number (400%), leaf number (586%),sucker fresh weight (386 %) and sucker dry weight (583%) significantlyincreased compared with control. the data obtained from the experimentshowed the potential of trichoderma and fe spray to enhance growth and developmentof spathiphyllum sp. in greenhouse conditions.
